Tiny Microcontroller Tester
A simple board to test out GPIO of your microcontrollers, using two rows of 0603 LEDs (one row for HIGH and one for LOW) and 0805 resistors.
If you have NO IDEA which LEDs to use - I recommend GREEN leds on the column furthest from the pins (to indicate a logic HIGH), and RED leds to indicate LOW. I used 1k resistors for the red, 4.7k for the green.
